Every color of light has the same identical speed in vacuum. Radio, X-rays,
microwaves, heat waves, and gamma rays also all have the same speed.
All colours travel at the same speed.

What happens to frequency does the speed of light ever change?
The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.
What percentage of the speed of light in vacuum is the speed of light in water?
When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.
How much speed of light is in a vacuum?
The speed of light in a vacuum is 186,282.397 miles per second or 670,616,629.2 miles per hour.
How is the index of refraction of a substance related to the speed of light in the substance?
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
What does the index of refraction best describe?
Refractive index is the ratio of speed in a vacumme as to speed of light in a medium. The slowest speed of light is attain by use extremely cold sodium atom as light medium and it is succeed to slow down the speed of light from 186,000 Mile/second to 38 Mile/hr (300,000,000 m/s -> 17 m/s). This account to refractive index of 17,621,000
Does light travel at its slowest speed when passing through a vacuum?
No, light is at its fastest in a vacuum.
What color travels the slowest?
The entire electromagnetic spectrum travels at the same speed. The speed of light.
Which color moves slowest through the spectrum?
Colors don't "move through the spectrum". Light of different colors has the same speed in a vacuum. In transparent materials such as glass or water, there are slight differences in speed, but that depends on the materal.
Does laser light color affect the speed at which it travels?
No the speed of light is independent of the color. The speed of light is dependent on the optical refractive index of the material or medium it is travelling through (in a vacuum light of any color has a speed equal to about 299,792,458 meters / second)
Does light travels slowest through space?
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
How fast different colors of light travel through a vacuum?
They all travel through a vacuum at the same speed - The speed of light.
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
Does the color of a laser affect the velocity?
Light always travels at the same speed, the speed of light. At least in vacuum. In a medium light will travel at a slower pace, and the speed decrease is dependent on the color (wavelength) of the light. This is because the refractive index (which determines how fast light can travel through a medium) is color dependent.
Is speed related to the color of a light wave?
No. All colors of light travel at the same speed in vacuum. Different colors represent light waves with different wavelengths (frequencies).
Is it true that a vacuum different color of light travel at different speeds?
No, that is not true. In a vacuum, all electromagnetic waves travel at the same speed.
Does the speed of light change in a vacuum?
No, not as long as the light stays in vacuum.No, it does not. That is where it has its maximum speed.
What happens to frequency does the speed of light ever change?
The speed of light IN A VACUUM is always the same. In substances other than the vacuum, the speed of light is usually slower than in a vacuum.
